Subject: unable to create class from constant
From: jason.sweat@gmail.com (Jason Sweat)

I ran across this today and it surprised me:

$ php -r 'define("X", "stdClass"); $x =3D new X; var_dump($x);';
Fatal error: Cannot instantiate non-existent class:  x in Command line
code on line 1

I tested on php 4.4.0, 4.3.8 and 5.0.3, with the result that all
versions exhibit the same behavior.

Clearly there is an easy work around:

$  php -r 'define("X", "stdClass"); $y =3D X; $x =3D new $y; var_dump($x);'
object(stdClass)(0) {
}

But I was wondering if anyone could enlighten me as to why php would
be upset interpreting the constant as the class name.  Thanks.
